摘要
针对输电线路状态监测业务的周期性特点和通信设备野外长时间工作要求,基于休眠唤醒机制提出了一种用于输电线路状态监测系统的低功耗通信技术及实现方法。线路上的所有通信设备在没有监测数据发送时处于休眠状态,而在传输数据前定时唤醒并完成数据收发。性能分析结果表明,该技术能够大幅降低通信设备的功耗,使得在蓄电池连续几周无法充电情况下,保证线路上所有通信设备的稳定运行。
On account of periodic characteristics of the services ot power line status surveillance ano the reqmrement oi long-rime working outdoors for communication devices, a low power communication technology and an implementation method based on the mechanism of sleep and awakening for power line status surveillance system are proposed. All communication devices on the lines without data transmission are in sleep status and they can be awaked timely before demand of data transmission and to finish it. Performance analysis shows that the proposed technology can significantly reduce the power consumption. Communication devices with this technology are able to operate steadily even the batteries are not charged for a few weeks.
